on a pair of axles 2, only one of which is shown in the drawings. The axles 2 are supported by wheels 3 and 4 which are nonrotatably secured to the axles and are spaced apart such a distance as to engage the opposite rails of a track. The base or frame of the machine is substantially rectangular in shape and mounted on a suitable base 5 is an electric motor 5*, although any other suitable type of motor may be employed. Extending upwardly from the forward end of the frame at opposite sides thereof are a pair of parallel bars 6 and 6 which lead upwardly therefrom at an angle as shown most clearly in Fig. 1. The bars 6 and 6 are then bent rearwardly to provide horizontal portions 7 and 7 and thence downwardly so as to provide rearwardly inclined portions 8 and 8. The ends of the bars 6 and 6 are secured to the frame as shown in Fig. 1 in any suitable manner, preferably by being welded thereto. Connecting the horizontal portions 7, 7 a of the bars 6 and 6 is an angle iron 8*. Carried by the angle iron 8 and rotatably mounted thereon are a pair of pulleys 9 and 10 which are connected with each other by means of a shaft 11 journaled in suitable bearings which are carried by angle iron 8", the purpose of which will hereinafter appear.

Extending upwardly from the base 1 are a pair of parallel bars or frame members 12 and 13 which are bent rearwardly to provide horizontal portions 14 and downwardly extending portions 15 and 16. Connecting the horizontal portions 14 is an angle bar 16 which is secured thereto in any suitable manner, preferably by welding. Secured on the angle bar 16 is a bearing 17 through which extends a shaft 18 to one end of which is non-rotatably secured a wheel 19. The opposite end of the shaft 18 is operatively connected with the shaft 11 through suitable reducing gearing (not shown). By turning the wheel 19 the pulleys 9 and 10 may be turned in either direction. Secured to the downwardly inc-lined portions 8 and 8 of the bars 6 and 6 are a pair of bearings 20 and 21 through which extends a shaft 22. Nonrotatably mounted on one end of the shaft 22 are pulleys 23 and 24 which are held STEEL TIE COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF thereon by a collar 25. Non-rotatably mounted on the opposite end of the shaft 22 is a pulley 26. Secured to the downwardly inclined portions 15 and 16 of the bars 12 and 13 respectively are a pair of bearings 27 and 28. Secured within the bearing 28 is a shaft 29, on which is non-rotatably mounted a pulley 30. Non-rotatably secured on the outer end' of the shaft 29 is a wheel 31. Qonnecting the pulleys 3-0 and 23 is a chain 32. Secured in the bearing 27 is a shaft 34 on which is non-rotatably,secured a pulley 35.. Non-roe tatably secured on the outer end of'the shaft 34 is a wheel 36 by means of which theshaft a mounted between a pair-of somewhat triangular plates 41, 42 whichare spaced apart and held'together by blocks 43 and angle irons 44, 45 and 46- which are preferably-welded tothe plates. The blocks 43 are spaced a slight distance from-the ends ofthe plates so that the plates project" slightly beyond the .blocks, as shown I in Fig. 5. Extending through the opposite ends of the plates 41 and 42 are a pair of pins 47, 48 on which are pivotally mounted pawls 49, 50. The lower ends of the pawls 49 and 50 are provided'with notches 51- and 52 which are adapted to engage the rails, as shown most clearly in Fig. 5. Y 7

Rigidlysecuredto and between the plates 41 and 42 are apair of brackets 53 and 54. The brackets 53 and 54 are shown in detaii in Figs. 6 and 7 and consist of a pair of plates 53 and 53 secured together by pins 55 and 56, 57 and 58. The ropes 3'9 and 40 extend around the pins55 and 56 and flexibly support the plates 41' and 42 together'with the mechanism carried thereby. Arranged with in the brackets53' and 54 are a pair of cranks 59 and which are shaped as shown most clearly in Figs. 2 and 5. The cranks 59 and 60 are pivotally mounted on the pins 57 and 58 asshown most clearly in Fig. 5. Pivotally connectedwith the cranks'59 and 60 are adjustable connectinglinks 6 1 and 62 which are connected with the cranks 59 and 60 by pins 63 and 64. The opposite ends of the links 61 and'62 are connected with the pawls 49 and 50 respectively by pins 65 and 66. The upper ends of the cranks 59 and 60 are each provided with bores or passageways 67 and 68 in which arewarranged threaded sleeves or bushings 69 and 7 0 through which a threaded shaft 71 extends.

Secured to the opposite ends of the shaft 71 are pulleys 72 and 73. For providing a driving connection between the shafts 22 and a 71 we provide chains 74 and 75'which connect pulleys 24 and 72 and 26 and 3'. It s will therefore be seen that by rotating the wheel 31 the pawls 49 and 50 may be moved outwardly or inwardly as desired. Secured to the plates 41 and 42' is an upstanding bar or lever 76 which has a notchtherein which engages over the shaft 71 between collars 77 and .7 8 provided on the shaft71, the purpose 7 of which will hereinafter appear.

Carried bythe plates 41 and 42 respectively are a pair of bearings 79 and 80 in which is journaled a shaft 81 on which is non-rotatably secured an eccentric 82. The shaft 81 is connected with the motor 5 by meanslof a flexible drive shaft 83. As the motorv is driven, a rotary motion will he given to the eccentric 82 which will impart a vibratory or pulsating motion to the plates 41 and 42 and the mechanism carried thereby as the plates 41 and 42 are suspended from the main frame by the flexible cables 39 and 40. Thesevibrations are transmitted to the rails through the medium of. the toggle 1 mechanism already described.

' -Carried by the shaft 22 adjacent the opposite ends thereof are two pairs ofcollars 84, 85 and 86,87. Disposed between these pairs of collars respectively'and engaging over the shaft 22 are a pair of bars or links 88 and 89. One end of each of the bars 88 and 89 is connected with the shaft 22 and the opposite ends of these bars are connected with brackets 90 mounted on thebrackets 53 and 54, the purpose of whichwill hereinafter appear.

- The operation of the device is as follows :.The vehicle is mounted on the track with the wheels resting on the rails and with the mechanism carried by the plates 41 and 42 supported above the rails. By turning the wheel 19, this mechanism is lowered until the blocks 43 engage the rails in the position shown in Fig. 5. By turning the wheel 31, shaft 71 will be turned through the medium of pulley 30, chain 32, pulley 23, shaft 22, pulleys 24 and 26, chains 7 4' and 75 and'pulleys 72 and 73. As the shaft 71 has threaded engagement with thersleeves 6 9 and 70 which are carried by the upper ends of the cranks 59 and 60, the cranks 59 and 60 will "be moved to the position shown in Fig. 5 and will engage the outer edges of the rails and firmly secure the mechanism to the rails. The motor 5 may then bestarted which will impart a rotary motion to the eccentric 82-, which in turn will impart a vibratory or pulsating motion to the plates 41 and .42 and the mechanism carried thereby. It will thus be seen-that a veryviolent motion will be imparted tothe rails and asthe rails are mounted on-ties, this vibratory motion will I in move the pawls 49 and out, of engagement with the rails. The vehicle can then be movedeither forward or backward as desired. The arms 88- and 89 serve to hold the plates 4-1 and 42. in the position shown in Figs. 1, 2 and 3 so that there will be no slack in the chains 74 and 75. These arms, to gether withbar 7 6 whichis disposed between the collars 77 and 7 8, prevent .the plates 41 and 42 fromswinging either longitudinally or laterally when the pawls are disengaged from the rails.

Various changes may be made in the details: of. construction and arrangement of parts withoutdeparting from the spirit of our invention and it is understood that the embodiment of the invention herein disclosed is merely illustrative and not to be considered in a limiting sense. Our invention is therefore limited only in accordance with the scope ofthe appended claims.
